Application February 17, 1945, Serial No. 578,368

It is common practice for painters to work on the outside of the walland the windows of a building.

It is common practice in such cases for painters to be supported on ascaffold that is hung from supports placed higher up on the building.

Buildings are frequently equipped with outside fire escapes, the floorsof which are made up of parallel bars of iron suitably spaced apart withopenings placed between them.

The object of this invention is to utilize the floors of such fireescapes for the purpose of supporting the scaffold from which thepainter must work.

Another object of the invention is to furnish a plate of special designwith a hole in the middle thereof, which plate will rest on two or morebars of the floor of the fire escape, and which can be turned on suchfloor.

Another object of the invention is to thread the hole in such plate witha female thread so that it will act as a nut when it is turned.

Another object of the invention is to shape the plate so that it isespecially thick or high around the hole. In other words, that part ofthe plate is made volcano shaped.

Another object of the invention is to provide said plate with a handleby which it may be easily turned.

Another object of the invention is to provide a hanger having a threadedrod or stem on the upper end thereof, which can be inserted between twobars in the floor of the fire escape and engaged with the threaded holein the plate by which the hanger will be supported.

Another object of the invention is to provide the hanger with a stirrupor triangular shaped extension at the bottom thereof on the horizontalmember of which a plank can be rested so that it will be supportedthereby.

Another object of the invention is to provide the horizontal member withtwo upwardly projecting points or pins which will engage in the bottomof the plank and will prevent the plank from skidding or slipping in thehanger if one i end of the plank is held higher than the other end.

These and other objects of the invention will be illustrated in thedrawings, described in the specification and pointed out in the claim atthe end thereof.

In the drawings:

Figure l is a perspective view of the plate which is placed on the floorof the fire escape.

Figure 2 is a perspective view of the hanger that 1 Claim. (01. 248-317)can be engaged with the plate for the purpose of supporting the plank.

In the drawings like reference numerals indicate like parts.

In the drawings reference numeral l indicates the plate that is placedon the floor of the fire escape. This plate is preferably rectangular inshape and is beveled on the ends thereof as indicated at 2 and 3 so thatit will engage two or more bars of the floor of the fire escape and sothat it can be turned on the fioor of the fire escape without catchingon or being obstructed by any of the bars on which it may rest or bywhich it may be engaged. 4 indicates the handle by which the plate maybe turned so that a wrench need not be applied thereto.

This plate is bulged up in the center volcano shape so as to give anextra thickness to the plate at the central part thereof. This part ofthe plate is perforated with a hole 6 which is threaded with a femalethread, which can be engaged by the stem of the hanger.

The hanger is shown in Figure 2 and consists of a single bar or rod 1threaded at its upper end with a male thread 8. This rod is bent onitself at the bottom so as to form a triangular shaped stirrup havingthe inclined sides 9 and [B on the opposite sides thereof and having ahorizontal bottom I I supported therefrom all formed preferably in onepiece. The side It is positively fastened to the side 9 as indicated atl2 by brazing or welding or in any other suitable manner.

The bottom of the stirrup is formed with shoulders I3 and I4 betweenwhich the plank is positively held so that it cannot move sideways, andon the bottom member I l is formed upwardly projecting pins l5 and It onwhich the plank rests and by which the plank is prevented from slippingendwise.

The hanger is put in place by first placing the part shown in Figure 1on the fioor of the fire escape. The rod 1 can be inserted up throughthe floor and engaged with the threaded hole 6 in the plate I. The plateI or the hanger can be turned several times until the threaded end 3 issuitably engaged with the hole 6. The hanger then is brought to thecorrect position and the plank is inserted in the stirrup and the end ofthe plank will be thereby supported.

The other end of the plank can be supported in a similar manner or inany other well-known manner as may be desired.

I claim:

A hanger for a painters scaffold comprising an upright bar threaded atthe upper end thereof,

a triangular shaped stirrup at the lower end of the bar, said stirruphaving two equally inclined side members and a horizontal bottom membersaid inclined sides being bent inwardly and downwardly before connectingwith the bottom member and forming shoulders on each side of the bottommember, upwardly projecting pins on said horizontal bottom member, aplate having a threaded openingtherein withwhich the threaded. endof'the .bar engages and from which it is supported, the top of the platebeing made volcano shaped around the threaded opening to.

increase the threaded engagement between the plate and the bar. and ahandle onthe-plate by which the plate is turned.
